Answer: maximum height= 40.8m
Explanation: shown in the attachment.
Goodluck
<span>I think they were also too skeptic to believe the continent did move or pull apart, even today do you believe that the
continents broke from one big flat plate, and that they pulled apart?
They also wonder what large force would be responsible for the movement.
It
was much later that evidences from plant and animal features that had
similarity from two different planets came up that scientists began
accepting the idea of continental drift.
And similar rock strata from two different opposite continents, showed similar rock strata.
All these evidences came up much later after Alfred Wengener.
So Alfred Wengener was honored Posthumously</span>
It could be stress or strain
The book's vertical position in the air is

where
. It reaches the ground when
, at a time
such that

So it takes the book 4 seconds to reach the bottom. The given initial velocity is irrelevant since it only has a horizontal component; vertically, the book is starting from rest.
To analyze the differences in acceleration of the two objects, a necessary formula/relation to remember here is force = mass * acceleration. Given the different data in the problem, we can solve for the acceleration of each object. This is shown below:
Force = 15 N
M1 = 25 kg
M2 = 50 kg
a1 = ?
a2 = ?
For object 1:
15 N = 25 kg * a
a = 0.6
For object 2:
15 N = 50 * a
a = 0.3
Therefore, the acceleration of Object B is half that of Object A.
